Meantime, the fallout is growing tonight over that four-letter world heard around the world. The well-known American diplomat who used the word when talking about our key allies. Well, she's now explaining herself, and ABC's chief white house correspondent Jonathan Karl on it again tonight. Reporter: More fallout on the f-bomb dropped by the top U.S. Diplomat for the eu. Today, Angela Merkel fired back, calling the salty disrespectable language totally unacceptable. More diplomatic embarrassment for president Obama. His choice to be U.S. Abam door to Argentina revealed he's never stepped foot in the country. Have you been to Argentina? I have not had the opportunity yet. Reporter: His main qualification, it seems, he raised more than $500,000 for Obama's re-election campaign. This after a top dollar donor was tapped to be ambassador to Norway. He didn't know what form of government it has. Why on Earth did president Obama nominate a guy that's never gone Norway? Raised nearly $850,000 for the president's re-election campaign. Oh. Reporter: And there's Colleen bell, a soap opera producer, named ambassador to Hungary. What are our strategic interests in hundrgary. In terms of our key priorities. Reporter: She had a hard time answering the most basic questions, but she raised $800 240ush ,000 to the Obama campaign. How much does it cost? There have been many, many political ambassadors, people that have come from a range of histories and backgrounds who have been very successful and worked very electively in these roles. So, wait a minute, Jon. You can become ambassador without having been? Reporter: The magic number is $500,000 or so, David, it seems. More than hatch of the noncareer ambassadors nominated by president Obama gave at least that much to his re-election campaign. Now, it's important to point out that all president boss that but president Obama has done more, more appointees to political supporters than bush or Clinton. All right, Jon Karl on the case again tonight. Jon, thank you.
